UNITED STATES PATENT (')EEICE JOHN OWEN SMITH, OF SAVANNAH, GEORGIA,ASSIGNOR TO HIMSELF AND JAMES CLEMENOE, OF SAME PLACE.

WINDOW-GUARD.

SPECIFICATION forming part of Letters Patent No. 250,592, dated December6, 1881. Application filed September 3, 1881. (No model.)

To all whom it may concern Be it known that I, JOHN OWEN SMITH,- of

Savannah,in the county of Chatham and State of Georgia, have invented anew and Improved Window-Guard and I do hereby declare that thefollowingis a full, clear, and exact descripwood, provided with lugs atthe top, adapted to enter seats formed in plates in the sides of thewindowframe, and provided with tongues of metal at the bottom,projecting at right angles to the frame inwardly, and adapted to enterhorizontal holes in the window-sill and be lockedv by set-screws or pinsinside, as hereinafter more fully described.

In the drawings, A represents a window or door frame, and B is theguard. This latter, as shown,is composed of a strong rectangular metalframe filled in with an open grating or other suitable metal net-work,and provided upon each of its sides, near its upper end,with lugs a (t,and having at its bottom end two in- Wardly-projectin g rigid metaltongues, b b, projectiug from the guard at right angles to its plane.Near the upper ends of the side frames of the window are arranged platesc, which are let in so that their faces opposing each other are flushwith the sides of the windowframe, and these plates are notched at theiredges with notches running inwardly and then upwardly, which notches areadapted to receive the lugs a a of the guard. In the sills C of thewindow-frame there are also horizontal holes d, running partially orwholly through the same, which receive the tongues b. These tongues haveperforations in their ends, which, when the tongues are in place in thesill, regi ister with vertical holes e in the window-sill, through whichscrews, bolts, or pins g may then be passed to lock the tongues in thesill.

To apply the guard, its lugs a. a are first entered into the notches, asshown in dotted lines in Fig. 2, the guard then slipped up until itstongues b are in line with the holes in the sill, and the tongues thenforced in and secured by the bolts or pins.

In making use of my invention the guard may be made to extend the fulllength of the window, or only part way, as may be desired, and it may bemade either in the form of an open metal grating or an impert'orateshutter. When applied to store-windows, also, the tongues-may pass allthe way through the sill and be secured by a pin, bolt, or key upon theinside edge of the sill, instead of bya bolt passing vertically throughthe latter.

Among the advantages of myinvention muy be mentioned the fact that theyare easily and quickly applied, and may as readily be taken down forwashing the windows, 85e., and they present, moreover, an effectualbarrier to the ei'orts of burglars, for it will be seen that not onlyare the fastenin gs all inside, but the screws which hold in the platesc are covered by the frame of the guard itself, so that they cannot begotten at to take off the plates.

Having thus described my invention, what I claim as new isl. Thecombination, with a wi ndow-frame having lug-seats at its upper ends andhorizontal holes through its sill, of a windowguard havinglugs at itsupper end and adapted to enter said seats, and rigid tongues projectingat right angles from its lower end, adapted to enter the holes in thesill, and means for securing the same, substantially as described.

2. The combination, with a window-frame having plates c, provided withundercut lugseats and horizontal and vertical holes through its sill, ofthe Window-guard having lugs a a near the top and rigid tongues b b atthe bottom, projecting at right angles, as described, and fasteningbolts, screws, or pins g, substantially as and for the purposedescribed.
